SCENARIO: Dr. Kushner is planning on conducting a study next semester. He is curious as to whether sleep deprivation is associated with poorer cognitive performance. For example, if you sleep poorly the night before a big exam, will you do worse? Dr. Kushner is especially curious about selective sleep deprivation, where people are kept from entering REM (rapid eye movement) sleep. Using an electroencephalograph (EEG) to monitor brain waves, he plans to let participants sleep until they enter REM sleep and then wake them. After the participants are awake for one minute, Dr. Kushner plans to let them return to sleep. As they enter REM sleep again, he will wake them again and follow the same procedure. He plans to do this through the entire eight-hour sleep session. The following morning, participants will be asked to take a sample SAT test. QUESTION: Kushner plans to tell his participants that the reason he is waking them up during the night is to recalibrate the EEG machine. This would be an example of which of the following?

Providing participants false feedback about their performance on an experimental task can be considered a form of deception. True or false?

SCENARIO: Dr. Rodriquez is considering conducting a study examining whether people who score higher on a measure of narcissism have poorer romantic relationships. One of her first tasks is to determine each participant’s level of narcissism. She decides to use a narcissism scale created by a colleague, the Donal Scale. Question 1 of the Donal Scale reads, “I think about myself much more than I think about others.” Question 2 of the Donal Scale reads, “I do not have a high opinion of myself.” Question 3 of the Donal Scale reads, “Other people think I am really special.” Participants are asked to respond to these items using a 1 (strongly disagree) to 5 (strongly agree) scale.   Before using the measure in her study, Dr. Rodriquez gives the measure to a group of participants on the first day of the semester and again on the last day of the semester. She then compares the scores between the two time points. This is a test of __________________. Dr. Rodriguez then examines the scatterplot of the data she collected on the first day of the semester and the last day of the semester. On the scatterplot, she sees that the dots are very close to forming a diagonal line. This scatterplot indicates _______________________.

SCENARIO: Dr. Sheffield is a clinical psychologist who specializes in treating pathological gambling. Pathological gambling is defined as being unable to resist impulses to gamble. Bothered by not having a good measure that he can give to clients to determine whether they are suffering from this condition, he creates a new measure of pathological gambling. The measure has 15 questions, and it takes 20 minutes to complete. To test his measure, Dr. Sheffield gives his measure to a group of people in Gamblers Anonymous (GA) and another group in Alcoholics Anonymous (AA). He finds that people in the GA group have higher scores on his new measure than people in the AA group. Why did Dr. Sheffield do this? What is this procedure known as?
